If you want to further manipulate or obtain a printed copy
follow the procedure described in the Data Download section
below.
Data Download
Selection “5” on the main menu “Data download” – allows
you to save a permanent record of the WMS-16’s stored data.
The data retrieval procedure is dependent on the
communications software program used. Using Microsoft
HyperTerminal, saving the program to disk is accomplished as
follows:
Ø
Press “5” at the main menu.
Ø
Then press “Y”
Ø
Now going to the top of the HyperTerminal
screen click on “Transfer”.
Ø
Click on “Receive File”; make sure the
protocol is XMODEM; enter the directory
and folder name where you want to store the
data.
Ø
Click on “Receive” and enter the file name,
e.g. weather01.
Ø
Click on “OK’’ and download will start.
Transfer time from a full memory may take up to eleven
minutes due to the error checking and the de-convolution of
the binary data to ASCII format. The down loaded file can be
entered into a spreadsheet or word processing program for
viewing or manipulating.
Note that the total contents of the memory is downloaded each
time the Memory Download procedure is invoked. The data
transfer is a nondestructive readout. The format of downloaded
data is shown in Figure 9.

Figure 9 WMS-16 Data Download
Clear Logging Memory
The final selection on the main menu lets you erase the stored
data from the WMS-16’s memory and begin logging fresh
data.
Once the WMS-16’s available memory is filled with data,
incoming records will replace the oldest stored data, and that
data will be erased. The CLEAR LOGGING MEMORY
option, on the other hand allows you to clear the entire
memory.
Remember: once the memory is cleared, the data cannot be
retrieved (unless it has been copied to a disk using the DATA
DOWNLOAD option).
To clear the logging memory:
Press “9” at the main menu (CLEAR LOGGING MEMORY).
The following message appears: Are you sure you want to
delete log file [Y or N]:
If you want to continue, type “Y”.
The following message will appear: Erasing Data Memory.
Please wait.
When the memory is erased, the WMS-16 returns to the
current observations screen and data logging resumes
